I am using sharelatex with a separate bibliography file. Some of the authors cited use a lowercase Polish l in there name. The LaTeX code for this symbol is \l{}. Here is a typical entry:

 @article{123,
AUTHOR = {Karo\'{n}ski, Micha\l{} and \L{}uczak, Tomasz and Thomason, Andrew},...}

However, sharelatex keeps interpreting the \l{} as an incomplete math symbol (according to the compiler error) and is not producing proper output in my bibliography. Here is the compiler error:

<inserted text> 
                $
l.99 Alan Frieze and Micha\l
                            {} Karo\'nski.
I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

BTW, \L{} and \'{n} both work just fine, along with all other foreign accents in names and titles in my bibliography, but the \l{} looks like \ell and everything after \l{} is in math mode.

Any ideas on work arounds out there?

  • It complies just fine on my desktop computer (I use TexShop on a Mac), but I am trying to work jointly with someone using sharelatex and I have never run into this sort of problem before. – Laars Helenius Feb 11 '18 at 04:15

    Your project on ShareLaTeX has a refeinition of \l to \ell somewhere. – egreg Feb 11 '18 at 08:38

    Unless you've somehow/somewhere redefined \l (and possibly \L), all you need to do is write {\l} and {\L} for BibTeX entries. The entire author field should read AUTHOR = {Karo{\'n}ski, Micha{\l} and {\L}uczak, Tomasz and Thomason, Andrew},. – Mico Feb 11 '18 at 08:42
  • I found this in my preamble: \renewcommand{\l}{\ell} Thanks for the help! – Laars Helenius Feb 11 '18 at 15:13
